Engine oil recommendation for CBR125R users.

I tried some of HONDA ULTRA oil,
WAKO'S PROSTAGE S(10W-30) and cheap oil(DIY shop brand).

First, i chosen HONDA ULTRA G1.

Owners manual indicates this oil and oil change cycle is 5000km.

but,i think 5000km is too long.
i've thought 2000km-3000km is the best cycle.

G1 is not so good.
but, not so bad.
very mediocre oil.
Vibration is generatedat 8000RPM or more.
So,if you wanna keep high rpm, you will may little tired.

In contrast,G4 is NO vibration.
And bery smooth at high rpm.
so,throttle response was shortened.

if you'll go to circuit I strongly recommend using this oil.


WAKO'S PROSTAGE S
This is worst oil of my experiences.
shift change feelings are too bad and often jumped out of gear.
and, speed of deterioration is fast. so increase oil change frequency.



cheap oils become dirty almost 1000km-1500km.
this is caused the faster deterioration and mineral oil.

on the other hand, High-end oils keep good condition up to 2000km-3000km.
maybe, additives to suppers degradation are effective.


if you choice cheap oil, please careful for oil change cycles.
